Be it known that I, HAnoLo D. WATER- HOUSE, a citizen of the United States, and a resident of Wollaston city of Quincy, county of Norfolk, and State of Massachusetts, have invented an Improvement 1n Tgnition Apparatus, of which the following description, in connection with the'accompanying drawings, is a specification, l ke characters on the drawings representing hke arts. p This invention relates to improvement in ignition apparatus for internal combustlon -eng1nes, and more particularly, though not.

exclusively, to an improved dlstributer.

In the drawings I haveelected to show a preferred form of one embodiment of my mvention as applied to a Ford motor car.

Figure 1 is an end elevation of a motor supplied with a preferred form of distributer' constituting one embodiment of my invention Fig. 2-is a horizontal section, partly in plan, through the distributor shown in ig. 3 is a vertical transverse section,

partly in elevation, on the line of though not necessarily, applied directly tothe cam shaft 6 of the car, in the same gen eral position as that. occupied by the commutator of the Ford'car. The amount of space between the time gear covercastin 7 and the fan 8 of the car is relatively slig t, and the distributer must be of peculiarly compact construction to avoid interference with the fan, while providing a sufiiciently long bearing to' be durable.

In the preferred form of my invention I have provided a sleeve 8 preferably secured to the shaft 6 by a pin 9, and carrying a distributer ring 10 mounted on any suitable interposed non-conductive rotating element 11, which also carries the distributer sector.

12 connected to the distributer ring 10 in any suitable way t ified by the wire 13. The sleeve 8' is pre erably extended to provide cam surfaces 14 and an extended beartributer.

To allwhmna'tmdyconcera:

by'those portions of the c lindricalsurface' of the sleeve 8 left a r cutting slots through the sleeve 8' corr ding to the number of cylinders to be fired by the disfor the sleeve 8', and also to provide bottom portions-for the cam surfaces 14, I- may, and preferably do, counterbolre the interior of the sleeve 8' to provide suflicient room for an interiorly threaded sleeve 16, which may be and referably is formed as a part of a cham cred nut adapted to en age the threads on the end of the cam shaf t 6. The nut 16 preferably bottoms against a shoulder 17 of the sleeve 8 thereby' pressing said sleeve firmly against the pin 9. The timing shaft 6, which is of course a half time shaft, the sleeve v8, distributer ring 10, distributer sector 12, the cam portions 14 and the nut 16 are, therefore, all locked together for joint rotation.

.I will now describe those portions of the distributer whichdo not rotate with the cam shaft 6. The housing for the distributer may comprisea casing 18 of any suitable non-conductive material, and preferably carries an electric connection 19, herein shown as a screw having its end adjacent the distributer ringlO for supplying current thereto, and a plurality of connections 20, 21, 22 and 23 for successively receiving the current from the distributer sector 12,'th0se connections being respectively connected to the spark plugs 24, 25,26 and 27 of the internal combustion engine. The casing 18 is preferably attached to the casting 7 in any suitable way, and is preferably provided with a bearing sleeve 28 engaging the exterior surface of the sleeve 8 through a considerable portion of-its length. The sleeve 28 is preferably slotted at 29 to receive the cam-engaging element 30, which is preferably carried bya breaker-arm spring 31 attached to the breaker-casing'32, which is preferably mounted for limited rotative movement about the sleeve 28. The cam-engaging element 30 controls the make and break of the primary circuit between the point 33 carried by the breaker-arm spring 31 and the stationary oint 34. The breaker casing 32 is preferab provided with a removable cover 35 secur to the breaker casing by the screw 36 and the screw 37 which may, as shown,

To advance or retard the spark, the entire breaker casing and parts carried thereby may be os- To hold the sleeve 28 andpa-r-ts carried thereby in place on the sleeve 8'-15, I may provide a disk 38 adapted to be pressed against the end of the sleeve 28 by a spring/39 carried by any suitable stationary portion of the motor such as the breather pipe 40 on the time gear cover 7 In Fig. 5 I have shown diagrammatically a preferred form ofwiringsystem for use in connection, with my invention in which 41 represents a generator, the wire 42 a primary wire from the generator leading through the switch 43, primary coil 44 and buzzer 45 to the stationary breaker point 34. From the stationary breaker point 34 the current passes to the movable breaker point 33 and thence through the breaker arm 31 in connection 46 to the motor round) and thence throu h the connection 4 to the generator 41. 'Ihe secondary circuit may be assumed to start from the motor (ground) at 48, passing through the secondary wiring 49, and secondary coil 50 to the connec tion 19 (Fig. 2), from which the current jumps to the distributer ring 10, which is connected with the distributer sector 12, from which the secondary current again jumps successively to the points 20, 21, 23-

and 22, connected to the spark plugs, of each of which one point is of course grounded on the engine, thus completing the circuit.

While I have shown and described a preferred form of one embodiment of my invention, it will be understood that major changes involvingomission, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims.
